The cooperation of patients is usually the main factor for any orthodontic treatment including clear aligners. Patients tend to cheat or underuse on recommended appliance wearing time, and poor compliance is a very frequent and inevitable problem resulting in relapse during clear aligner therapies. Compliance is a multifactorial problem: the softest material of the clear aligner materials indicates a 14-day protocol while for more rigid aligners from a 10 or a 7-day protocol depending on the amount of rigidity and comfort of the patient, the recommended daily wearing time is usually 22 hours or more, with this routine wearing protocol, an average tooth movement of 0.25 mm, 2° of rotation and 1° of root torque per tooth can be achieved. Some factors influenced by patient-related issues such as gender, age, educational background, type of personality traits, the patient expectations of smile appearance, the self-perception of pain as well as appliance-related factors such as softer materials of aligner making it easier to fit and to wear with lesser pain during therapy, the number of attachments as well as overall sets of clear aligners to be worn. Clinician-related factors such as rapports, orthodontic expertise and oral hygiene education and control through proper followups.

You will wear each set of aligners for 20 to 22 hours a day, changing to a new set of aligners every 1 to 2 weeks, as directed by your doctor. Each set of aligners will gently and gradually shift your teeth into place, according to your treatment plan, until you reach your beautiful new smile.

Patients are usually instructed to wear each clear aligner at least 22 hours a day for 7 to 14 days. With this routine wearing protocol, an average tooth movement of 0.25 mm, 2° of rotation and 1° of root torque per tooth is possible via each appliance.

Ultimately, the choice of aligner wear protocol should be based on a combination of factors including the patient's needs and preferences, the complexity of the orthodontic case, the clinician's expertise, and any specific requirements of the treatment plan. Regular monitoring and adjustments may be necessary regardless of the chosen protocol to ensure optimal progress and outcomes.
